Avoid siphoning
NOTICE
Siphoning effect
Tanks overflowing/leaking = oil spill
►
Remove the ends of the hoses from the tanks after operation.
If there is a height difference (
Δ
h) between the suction-side and pressure-
side tanks, a suction effect can develop in the hose that is lower down, caus-
ing the fluid levels to equalize in accordance with a principle of communi-
cating vessels (siphoning). This siphoning effect also occurs when fluid is
pumped in a pre-pressurized tank.
When the unit is switched off, the height difference/primary pressure can
cause flow to occur both in the feed direction and against the feed direction
and fluid can leak uncontrollably.
